2) Open Lamp Protection (OLP) Mode
After the lamp has successfully ignited, the FAN7532
enters run mode. In this mode, if one of the cathodes
isn’t correctly connected to the ballast, the ballast stops
operation for safety until the lamp is changed and a new
one is connected between the lamp and the ballast. As
soon as the voltage of OLP pin exceeds 2V, the IC

enters the protection mode. However, the FAN7532 out-
puts are only disabled in this mode. To exit protection
mode, the lamp must be replaced or correctly connected
to the ballast.

8. PCB Layout Guides
Component selection and placement on the PCB is very
important when using power control ICs. Bypass the V CC
to GND as close to the IC terminals as possible with a
low ESR/ESL capacitor, as shown in Figure 20. This
bypassed capacitor can reduce the noise from the power
supply parts, such as a startup resistor and a charge
pump. The GND lead should be directly connected to the
low-side power MOSFET using an individual PCB trace.
In addition, the ground return path of the timing compo-
nents (CPH, CT, RPH, RT) and V CC decoupling capaci-
tor should be connected directly to the IC GND lead and
not via separate traces or jumpers to other ground traces
on the board. These connection techniques prevent
high-current ground loops from interfering with sensitive
timing component operations and allow the entire control
